MACHINE FOR PERFORATING MUSIC=BANDS.

SPECIFICATION forming part of Letters Patent: No. 389,872, dated September 25, 1888.

Application filed June 7, 1887. Serial No. 242,566. (No model.) Patented in France Fcbruary25,1885, No. 167,277; and in Eng land May 17, 1887, No. 7,194.

To aZZ whom it may concern.-

Be it known that l, JULES CARPENTIER, a citizen of the French Republic, residing in Paris, France, have invented certain new and useful Improvements in Machines for Perforating Music-Bands, of which the following is a specification.

This invention is the subject of a patent in France,No. 167,277, dated February 25, 1885, and in England,No. 7,194, dated May 17, 1887.

This invention relates to machines for preparing the perforated bands of paper employed for actuating automatic musical instruments.

In my application for patent for apparatus for mechanically playing keyed musical instruments filed May 28, 1887, Serial No. 239,655, I have described an automatic musical apparatus employing a band of perforated paper, and which apparatus I term a Melotrope. This apparatus presents the advantages over others of the same classsuch as the pianista, which are,like it,automatic auxiliaries of the pianoof being more simple, more convenient, and of cheaper construction. N evertheless the use of the melotrope would be relat-ivel y limited if it were not possible to procure at a moderate price the perforated bands which translate for thcinstrument the musical airs to be played on the piano.

The object of my present invention is to provide an improved and simplified machine by means of which the perforation of automatic musie-bands shall be accomplished cheaply and automatically. In machines for this purpose a series of punches is provided arranged in a line facing the band of paper to be perforated, which is fed through the machine, and the action of these punches in perforating this band of paper is determined by means of a band of paper previously perforated, which band is called the type-band, and the perforations in which are by the action of the machine reproduced identically in the new band to be perforated. The latter may be of paper, card-board, metal, or other material, and one or more bands may be superposed and punched simultaneously.

In my machine the punches are driven by hammers which are reciproeated up and down and are moved into or out of the path of the punches through the action of feelers or fingers which come against the type-band, and which, when they encounter the imperforate portions thereof, hold the hammers out of en gagement with the punches; but when any of the feelers are displaced by entering the perforations in the type-band the hammers corresponding to them are thereby moved into the path of the punches and the corresponding punches are driven and caused to punch the paper. The feelers do not participate inthe driving movement of the hammers, but remain stationary,orsubstantiallyso,duringsuch movement. The connection of the feelers with the hammers is of such character that the feelers move the hammers only in lateral direction and do not interfere with the longitudinal movement of the hammersin punching. The hammers are driven simultaneously and are retracted after each punching movement by the reciprocation of a frame to which they are connected.

I will now proceed to describe the construction of my improved machine with reference to the accompanying drawings, wherein- Figure l is a side elevation of the machine. Fig. 2 is a front elevation thereof. Fig. 3 is a plan thereof; and Fig. 4 is a vertical transverse section cut in the plane of the line 4 4 in Fig. 3, and showing the most essential operative parts upon a larger scale than the preceding figures.

The machine is driven through the medium of a belt-pulley, A, fixed on the end of a shaft, B. To the opposite end of this shaft is fixed a disk, 0, carrying an eccentric pin or stud, D. At each turn of the shaft B this stud D engages one of the notches of a toothed wheel, E, and turns the latter the space of one tooth. The wheel E is held after each intermittent movement by an arresting device consisting of a friction-roller, F, carried at the end of an arm, G, and pressed toward the wheel by a coiled spring, H, Fig. 3, at the pivot of the arm. The roller F enters between two of the teeth on the wheel E and holds the latter stationary until itis moved by the stud D, whereupon the roller F is depressed by the passage of one tooth and returns again into the next notch, where it holds the wheel until the next movement. The shaft E, on which the wheel E is fixed, carries a pinion, g, which gears with a toothed wheel, it, fixed to a feeding roller, K, which is covered with indiarubher to give ita frictional surface. Above the roller K is a similar roller or cylinder, L, of metal or other material, formed with peripheral grooves. Between these two rollers K and L pass the two bands of paper-the typeband or master-band i and the band of paper to be perforatethj. The former passes around the grooved cylinder L, while the latter passes in a horizontal direction over the top of the table \V. By means of the mechanism thus far described, which I will refer to as the feeding mechanism, both bands are fed through the machine intermittently, makin g a short forward movement to each rotation of the drivingshaft Y Y are the punches for perforating the sheet j. They are mounted in vertical holes or grooves in an upright fixed frame, Q, which stands above the table XV. Each punch has a projecting head, X, forming an overhanging shoulder, under which projects a ledge, Z, as shown in Fig. 4, forming part of a verticall y-reci procatin g frame, T,which is mounted to slide in vertical-guides U U at the opposite ends of the frame Q. The frame T is continuously rcciprocated by means of pitmcn or connecting rods V V, which are connected to it at their upper ends, and to cranks or eccentrics k 7.: on the driving-shaft B at their lower ends.

The frame 1 is the hammer'carrying frame, To it are pivoted as many hammers O O as there are punches Y Y, each hammer being arranged directly over its respective punch, and all being pivoted on an axis, R, and pressed rearwardly by springs S S. Their construction is best shown in Fig 4. Each hammer O is capable of a slight forward or rearward motion at its lower end. It is shown in full lines in Fi 4. in its forward position. \Vhen in this position,it clears the head X of the punch during its downward movement, and the punch is not driven; but when in its backward position,as show 11 in dotted lines,itsend encounters the head of the punch and in its descent forces down the punch and causes the latter to perforate the paper. Behind each hammer O is a sliding pin.-or rod, P, which moves freely in a horizontal hole in the frame Q. The forward end of each rod P bears against the hammer O, and its rear end bears against a lever, M, which is pivoted on an axis at N. This lever is formed with a finger or projection, s, which comes in contact with the type-band '6, and constitutes the feeler hercinabove referred to.

It will be understood that there are as many punches Y Y, hammers O 0, pins P P, and feelers M M as there are rows of perforations in the respective music-bands. Each set or group of these devices operates independently of every other set or group thereof. Fig. et

shows one set or group-that is to say, one feelcr M, and one punch Y, with the hammer which operates this punch, and the intermediate devices by which this hammer is controlled by the feeler. It will also be understood that the grooves in the cylinder L correspond in number and arrangement with the rows of perforations in the musicsheeti, and with the fingers s s of the feelers M M, so that each fingcr 8 comes in contact with the type-band i in line with a row of perforations therein, and when it encounters a perforation it is able to move into the same by entering the corresponding groove in the cylinder L.

The feelers M M are pressed to ward the typeband '1. by the springs S S, the pressure of which is transmitted to them through the medium of the hammers O O and sliding rods 1? P. The feelers M M are retracted by means of a cam, c, which rotates synchronously with the driving-shaft B, being driven therefrom through gears d, c, andf, as shown in Fig. 2. This cam acts against a projecting head, a, at the top of each feelcr M, and serves to move forward to the position shown in full lines in Fig. 4 all the feelers M M and hammers O 0, thus retracting the fingers s 3 clear of the type-band i. This being done, the feeding operation takes place, by which the bandsiand j are advanced a short distance. At the same instant the hammers O are elevated, their frame T being in its highest position. The feelers M M are then released by the abrupt side I) of the earn 0 clearing their heads a (t. Thereupon all the feelers move backward, some of them being instantly arrested by the contact of their fingers s with uuperforated portions of the type-band i, while some of them are permitted to move entirely back by reason of their fingers s dropping into perforations in the type-band. In the latter case the hammers O O,correspondiug to these feelers, are moved into the position shown in dotted lines in Fig. 4, with their lower ends over the heads of the punches Y Y. The frame T then moves down, whereupon thehammers O O,which have been thus displaccd,' drive down the corresponding punches Y Y and cause them to perforate the paper band j, while the punches corresponding to the hammers which were not displaced remain elevated. On the upstroke of the frame T the punches which have been forced down are raised again to their normal positions by means of the ledge Z, which in its ascent takes under the projecting portions of the heads X X of the punches. Meanwhile the cam c has been retracting the feelers M M, and by the time the upstroke of the frame T is nearly completed has moved them clear of the typeband i, whereupon another feed takes place, and the operations described are repeated. Thus to each revolution of the driving-shaft the paper bands are fed forward a little, the feelers are brought into contact with the typeband, and if any of them enter perforations therein the punches corresponding to such feelers are driven through the unperforated band and punch corresponding perforations therein. In the case of a long perforation or slot, which is to produce aprolonged note, the feeler corresponding thereto will enter it a number of times successively proportionally to its length, and the corresponding punch will be driven an equal number of successive times and will punch holes which, so to speak, overlap each other, the result being that an elongated perforation is produced in the band j, the length of which is proportional to that in the band t. Thus by the operation of my machine the band j is perforated with holes which correspond in arrangement and in rela tive length to those in the type-band t'.

It will be understood that my invention is susceptible of considerable modification without departing from its essential features. For example, the hammers and punches may be differently constructed; the feelers need not be levers, but may be any device which may be controlled by the perforated typeband and which will suffice to control the action of the hammers on the punches, and the connection between the feelers and the hammers may be effected by different means. The type-band for governing the action of my machine need not necessarily be a perforated band, but might be an embossed band, or a band formed with projections; or it might be a cylinder having projections, all of which are well known in the art. All of these modifications come within the domain of mechanical construction and adaptation, and do not affect the essential features of my invention.

I claim as my invention the several improvements in machines for perforating bands for automatic musical instruments, defined as follows, substantially as hereinabove specified, namely:

1. The combination of aseries of punches, a corresponding series of hammers for driving said punches, and a corresponding series of feelers arranged to be pressed against the typeband which controls the machine and co-opcrating with said hammers but distinct therefrom, so that they need not participate in the punching movcment thereof, substantially as set forth.

2. The combination of aseries of punches, a corresponding series of hammers for driving said punches, and a corresponding series of feelers arranged to be pressed against the typeband which controls the machine and distinct from said hammers, so that they need not participate in the punching movement thereof, and intermediate connections between said hammers and feelers and in operative contact therewith, whereby when any feeler is displaced by entering a perforation in the typeband it causes, through said intermediate connection, the corresponding hammer to be displaced into the path of its punch, thus driving the latter, substantially as set forth.

3. A series of punches, a corresponding series of hammers for driving the punches, and a corresponding series of feelers arranged to be pressed against the type-band which controls the machine and distinct from said hammers, so that they need not participate in the punching movement thereof, and intermediate connections between said hammers and feelers and in operative contacttherewith,whereby when any feeler is displaced by entering a perforation in the type-band it causes,through said intermediate connection, the corresponding hammcrto be displaced into the path of the punch, thus driving the latter, in combination with springs pressing against the respective hammers and acting through them and said intermediate connections on the feelers, and a restoring mechanism acting on the feelers and pressing them back to free them from the type-band after each punching, and thereby, through them and said intermediate connections, restoring the punches, substantially as set forth.

A series of punches, a corresponding series of hammers for driving said punches, a corresponding series of feelers arranged to be pressed against the type-band which controls the machine and distinct from said hammers, so that they need not participate in the punching movementthereof,andintermcdiateconnections between said hammers and feelers,\vhereby when any feeler is displaced by entering a perforation in the type-band it causes,thrugh said intermediate connection, the corresponding hammer to be displaced into the path of its punch, thus driving the latter, in combination with springs acting to press the respective feelers toward the type-band, and a cam acting to press back the feelers and free them from the type-band, and then to release them and permit them to be pressed back against the same, substantially as set forth.

5. The combination of aseries of punches, a

corresponding series of hammers for driving the punches, a corresponding series of feelers arranged to be pressed against the type-band which controls the machine and distinct from said hammers, so that they need not participate in the punching movement thereof, a connection between the respective hammers and feelers,consisting ofpins sliding longitudinally in guiding-holes, and arranged with the one end abutting against the hammers and the other end against the feelers, and springs ressin a ainst the res ective hammers and P a s acting through them and the pins on the feelers, whereby when any feeler is displaced by entering a perforation in the type-band the corresponding pin is relieved and the corre sponding hammer is permitted to be displaced by its springinto the path of its pu nch, whereby it is caused to drive the latter.

6. The eombinatiomwith afeeding mechanism for advancing the band of paper, of a series of punches having shoulders thereon, a corresponding series of hammers for driving said punches, a reciprocating frame for driving said hammers and having alcdge taking under the shoulders on said punches to restore the latter after they have been driven, a series of feelers independent of said hammers, and intermediate connections between said levers and feelers and in operative contact there with, whereby the displacement of the feelers will effect a lateral displacement of the corresponding hammers and bring the latter into the paths of the punches, substantially as set forth.
